CERAMIC MEMBER AND METHOD FOR MANUFACTURING CERAMIC MEMBER

摘要

PURPOSE: A manufacturing method of a ceramic member is provided to prevent the cracks in processing and to facilitate the processing of a ceramic member by manufacturing the ceramic member while controlling the molar ratio of ZrO2 and Al2TiO5 and sintering temperature. CONSTITUTION: A manufacturing method of a ceramic member comprises Al2TiO5 and zirconia oxide. The molar ratio of ZrO2 to Al2TiO5(Al2O3/TiO2) is 1/1 - 4/1, or 2/1. A manufacturing method of a ceramic member comprises a step of arranging ZrO2 powder, Al2O3 powder, and TiO2 powder; a step of mixing ZrO2 powder, Al2O3 powder, and TiO2 powder; and a step of sintering the mixture. The sintering temperature is 1400-1600 >=. [Reference numerals] (AA) Second example(ZrO_2/Al_2TiO_5 molar ratio=1/2); (BB) Sintering temperature 1500°C;
